The Schneider Electric iSW A9S60232 isolator switch is a modular switching device from the Acti9 series, specifically designed for industrial applications. It is a 2-pole isolator switch with a rated current of 32 A and an operating voltage of 415 V AC. The device is designed for mounting on a DIN rail and complies with the IEC/EN 60947-3 standard, which applies to isolator switches in industrial environments. Its modular design enables flexible integration into existing switchgear, with the device occupying a width of two modules (each 9 mm). Dimensions are 70 mm length, 18 mm width, and 77 mm height. The electrical life expectancy is 30,000 switching operations, indicating high durability and longevity.

Applications
This isolator switch is intended for use in industrial electrical installations where safe and reliable disconnection of power supply is required. It is particularly suitable for systems exposed to high mechanical and electrical stress, such as in manufacturing, machine building, or automation technology. The disconnection does not provide electrical protection, but serves physical isolation of circuits to enable safe maintenance or inspection work.

Functions and Features in Detail
The device features a snap-action mechanism that ensures wear-resistant switching of contacts and extends contact life. Connections are made via single connection terminals on the top and bottom of the device, suitable for both cables and pin-type busbars. Mounting is tool-free via a clip fastening on the DIN rail, speeding up and simplifying installation. The switching position can optionally be indicated by stackable auxiliary modules, such as an OF module (showing On"/"Off). Additional optional modules include fault tripping (SD), load current tripping (MX, MX+OF), and undervoltage tripping (MN, MNs, MNx), which can be added according to requirements.

Technology Explained Simply
The iSW A9S60232 isolator switch is not a circuit breaker in the sense of a protective device, but serves exclusively for disconnecting the circuit. It does not have integrated protective functions such as thermal or magnetic tripping. Switching is mechanical, with the snap-action mechanism ensuring gentle and even switching of contacts to minimize wear. The insulation voltage is 500 V AC, ensuring safe electrical isolation even at higher voltages. The operating voltage of 415 V AC is typical for industrial three-phase networks in Europe.

Compatibility and Accessories
The device is compatible with various optional accessory modules. These include auxiliary switches such as the A9A15096 (OF 1W for iSW 20-32A), which indicates the switching position. Other compatible modules include multiple connection terminals (19091, 19096) and locking elements (26970), which allow additional securing of the switching position. The isolator switch A9S65240 (2-pole, 40 A, 240 V AC) is also available in the range, but is not directly compatible with the A9S60232, being a separate model.

Mounting and Installation
Mounting is tool-free via a clip fastening on a DIN rail, enabling quick and secure fixation. Connections on the top and bottom of the device are designed for cables and pin-type busbars, allowing flexible wiring. The modular design allows easy integration into existing switchgear. Mounting is done on the left side of the device, with modules secured by simply snapping them into place on the side.

Operational Advantages
The iSW A9S60232 isolator switch offers high mechanical and electrical life expectancy, making it suitable for demanding industrial environments. Tool-free mounting and modular expandability with optional auxiliary modules increase flexibility and maintainability. The snap-action mechanism ensures long contact life, and DIN rail mounting enables standardized integration into enclosures. Compliance with the IEC/EN 60947-3 standard ensures reliability and safety in industrial use.
